Engineering Mutation Clones In Mammalian Cells With Crispr/Cas9, Zijun Huo, Jian Tu, Rachel Shoemaker, Dung-Fang Lee, Ruiying Zhao

Faculty, Staff and Student Publications

CRISPR, Clustered Regularly Interspaced Short Palindromic Repeat, as a powerful genome engineering system, has been widely accepted and employed in gene editing of a vast range of cell types. Compared to zinc finger nucleases (ZFNs) or transcription activator-like effector nucleases (TALENs), CRISPR shows a less complicated process and higher efficiency. With the development of different CRISPR systems, it can be used not only to knock out a gene but also to make precise modifications, activate or repress target genes with epigenetic modifications, and even for genome wide screening. Here we will describe the procedure of generating a stable cell line …

Poly(A) Probe Hcr Rna-Fish Specifically Marks Pyriform Nurse Cells In The Brown Anole Lizard Ovary, Zoe B Griffin, Bonnie K Kircher, Richard R Behringer

Faculty, Staff and Student Publications

Hybridization chain reaction RNA-fluorescent in situ hybridization (HCR RNA-FISH) is a powerful and increasingly used method for visualizing gene expression in cells and tissues. A probe set against polyadenylated RNA (poly(A)) is often used as a positive control for RNA integrity and staining quality. While optimizing this technique in the ovary of the brown anole lizard (Anolis sagrei), we found that the poly(A) probe produced a strikingly specific and intense signal in pyriform cells, a specialized lizard-specific nurse cell type. This staining pattern was found in both whole-mount samples and paraffin sections, suggesting that poly(A) signal intensity can serve as …

Nemolizumab As An Alternative Therapeutic Option For Indolent Systemic Mastocytosis, Sezim Minbaeva, Stephen K Tyring

Faculty, Staff and Student Publications

Indolent systemic mastocytosis (ISM) is a clonal mast cell disorder characterized by recurrent symptoms that can persist despite treatment with antihistamines, leukotriene antagonists, and mast cell stabilizers. Treatment options are limited when symptoms remain refractory, and avapritinib is contraindicated or declined. We describe the case of a 62-year-old female with an 11-year history of ISM who developed worsening pruritus and urticaria despite extensive conservative and biologic therapies, including topical corticosteroids, hydroxyzine, montelukast, omalizumab, and dupilumab. Given her history of stroke, she declined avapritinib. Nemolizumab was initiated with a 60 mg loading dose followed by 30 mg every four weeks. After …

A Phenomenological Analysis Of Sense Of Belonging Among Community College Educators, Muhammad Owais Aziz

EVMS School of Health Professions Theses & Dissertations

This phenomenological study explored the complex phenomenon of sense of belonging (SB) among diverse health professions educators (HPEs) and non-health professions educators (non-HPEs) at a Canadian community college. SB, as a dynamic construct shaped by an individual's perception of being valued and respected, is influenced by personal preferences and by complex interactions with the individual's surroundings. To better understand SB and foster a more inclusive environment for diverse educators, it is necessary to investigate SB among these educators. This qualitative study used eleven semi-structured interviews and seven steps of data analysis. The results of this study can inform strategies, policies, …

Identification Of Distinct Subtypes In Immune Tolerance After Hematopoietic Cell Transplantation Using The Prospective Able1.0 Pediatric Study Cohort, Bernard Ng, Shalini Shenoy, Et Al.

2020-Current year OA Pubs

The lack of immune tolerance after hematopoietic cell transplantation (HCT) can result in chronic graft-versus-host disease (cGvHD), which is the primary nonrelapse limitation of successful HCT. To date, immune tolerance has been considered a single biological entity, but we hypothesized that post-HCT immune tolerance could develop through multiple pathways. Using the ABLE network database, which comprises measurements of 75 cell populations, 10 cytokines and chemokines, lymphocyte population telomere length, KRECs and TRECs, and 132 metabolites from the largest pediatric cGvHD cohort (n = 241), we applied clustering analysis to patients with primary immune tolerance (PIT; no acute GvHD [aGvHD] or …

CC-chemokine ligand 2 (CCL2) is involved in the pathogenesis of several diseases associated with monocyte/macrophage recruitment, such as HIV-associated neurocognitive disorder (HAND), tuberculosis, and atherosclerosis. The rs1024611 (alleles: A>G; G is the risk allele) polymorphism in the CCL2 cis-regulatory region is associated with increased CCL2 expression in vitro and ex vivo, leukocyte mobilization in vivo, and deleterious disease outcomes. However, the molecular basis for the rs1024611-associated differential CCL2 expression remains poorly characterized. It is conceivable that genetic variant(s) in linkage disequilibrium (LD) with rs1024611 could mediate such effects. Previously, we used rs13900 (alleles: C>T) in the CCL2 …

Chronic psychosocial stressors contribute to cardiovascular disease (CVD) and related risk factors, particularly in under-resourced communities. Psychosocial stressors activate the hypothalamic-pituitary-adrenal (HPA) axis, leading to sustained cortisol action on immune cells. Natural killer (NK) cells are altered in distribution and function in cardio-metabolic diseases; however, pathways linking cortisol as a marker of chronic stress to NK cell dysfunction remain understudied. We recruited 186 African American women from the Step It Up Community-Engaged, Digital Health Physical Activity Intervention study and collected cortisol, NK cell measures, and psychosocial stress measures using validated questionnaires, including chronic stress and loneliness. Plasma cortisol levels were …

Department of Biomedical and Translational Sciences Faculty Publications

Substance use disorders (SUDs) remain major public health concerns worldwide, particularly in developed countries. SUDs are characterized by persistent neuroinflammation and synaptic dysfunction in the brain. Despite decades of extensive investigation, the detailed mechanisms underlying SUDs remain elusive. Ferroptosis is a highly regulated cell death process deeply affected by iron metabolism, lipid peroxidation, reactive oxygen species (ROS) production, and antioxidant systems. It has been implicated in multiple neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, multiple sclerosis, and ischemic stroke. Recently, emerging evidence has highlighted the role of ferroptosis in drug-induced pathological changes. Various types of abused substances including alcohol, cocaine, …

Senescent Fibroblasts In Aging And Pulmonary Fibrosis, Sara B. Palega, Aiwei Y. Borengasser, Yan Y. Sanders

Microbiology & Molecular Cell Biology Faculty Publications

Aging is a major risk factor for many chronic lung diseases, including Idiopathic Pulmonary Fibrosis (IPF), a fatal and incurable disease characterized by progressive fibrotic remodeling. Age-associated structural alterations, impaired regenerative capacity, and dysregulated cellular signaling collectively create a pro-fibrotic microenvironment. A central driver of this pathological shift is the accumulation of senescent cells, which undergo irreversible growth arrest and develop a robust pro-inflammatory senescence-associated secretory phenotype (SASP). Emerging evidence identifies senescent lung fibroblasts as critical mediators of IPF pathogenesis. These cells promote excessive extracellular matrix deposition, myofibroblast differentiation, and tissue stiffening, while simultaneously impairing epithelial regeneration. Together, these effects …

Single-Cell Transciptomic Analysis Reveals Age-Related Remodeling Of Brain Endothelial Cells, Hai Duc Nguyen, Summer Siddiqui, Diana G. Bohannon, Robert V. Blair, Hong-Wen Deng, Alexandre Prat, Woong-Ki Kim

Microbiology & Molecular Cell Biology Faculty Publications

Blood–brain barrier (BBB) integrity naturally declines with age. Brain endothelial cells (ECs) and pericytes (PCs) form the BBB, and aging impairs tight junctions, likely via altered PC-to-EC signaling. However, the molecular mechanisms underlying this impairment remain unclear. Using single-cell RNA sequencing, we profiled 68,316 brain ECs expressing 15,564 genes from young and old mice. Unsupervised clustering and annotation revealed five distinct EC subtypes—Capillary EC1, Capillary EC2, Arterial EC, Venous EC1, and Venous EC2—defined by marker genes Mfsd2a, Plvap, Bmx, Nr2f2, and Vcam1, respectively. Aging shifted EC subtype distribution, with reduced Capillary EC1 (45% vs. 57%) and increased Arterial …

All Peer-Reviewed Publications

Introduction:

Human African trypanosomiasis (HAT), caused by Trypanosoma brucei rhodesiense, is categorized as acute due to rapid disease progression but presents varying clinical outcomes. Although the mechanisms underpinning differential clinical progression are poorly understood, both host and parasite factors are implicated. Therefore, we sought to elucidate roles of primate host factors in mediating varying T. b. rhodesiense infection outcomes.

Methods:

Here, we assessed the roles of selected host cytokines in disease progression using a tsetse-mediated infection in a non-human primate (NHP) vervet monkey model that closely mimics HAT and natural infection. We quantified eight cytokines, including TNF-α, IFN-γ, IL-10, IL-6, …

The Experiences Of Black Women’S Maternity Care And Its Effects On Pregnancy Outcomes, Joy O. Osaghae

West Chester University Graduate Theses, Dissertations, and Final Projects

Health disparities in maternal health are a significant challenge to the public health of the United States, and Black women have double the morbidity and mortality rates of maternal illnesses in comparison with White women. These inequalities persist across socioeconomic levels, highlighting systemic inequities within the healthcare system. Some published studies have focused on quantitative outcomes, but few have examined Black women's lived experiences and their impact on pregnancy outcomes. This paper fills this gap by discussing the maternity care experiences of Black women in Philadelphia, Pennsylvania. Drawing on Critical Race Theory and Intersectionality Theory, this qualitative phenomenological study explored …

Development Of A Clinical Prediction Model To Guide The Selective Use Of Spect/Ct In Papillary Thyroid Cancer, Liya Zhu, Junik Son, Lu Wang, Haifeng Hou, Byeong Cheol Ahn

Research outputs 2022 to 2026

Background: Radioiodine whole-body scan (WBS) is routinely performed after radioiodine therapy in papillary thyroid cancer (PTC), but its two-dimensional nature limits anatomical localization. The addition of single-photon emission computed tomography/computed tomography (SPECT/CT) improves diagnostic accuracy; however, routine use exposes patients to additional radiation, longer imaging time, and higher costs. This study aimed to establish a predictive model to identify which patients with PTC are more likely to benefit by adding SPECT/CT imaging after WBS, enabling selective rather than routine use. Methods: This retrospective study included 265 patients with pathologically confirmed PTC who underwent postoperative radioiodine therapy followed by WBS and …

Emerging Blood-Based Biomarkers For The Detection Of Parenchymal Brain Metastasis: Current Progress And Future Perspectives, Désirée Sexauer, Elin S. Gray, Helen Rizos, Pauline Zaenker, Aaron B. Beasley

Investigating The Immunostimulatory Potential Of Dsrna-Silk Nanoparticle Complexes In Melanoma, Samuel J. Peters

Theses and Dissertations (Comprehensive)

The rate of resistance to immune checkpoint inhibitor treatment in metastatic melanoma is quite high, with an overall rate of 70%. Melanoma achieves these high rates of resistance by suppressing the immune response in the tumour microenvironment (TME), making them immunologically “cold”. The type 1 interferon response could be leveraged to initiate immune responses in melanoma, making their “cold” TMEs “warm” again. Double-stranded ribonucleic acids (dsRNAs) are potent activators of an innate immune response; however, they are susceptible to degradation by nucleases present in the body and need a carrier. Silk nanoparticles (SNPs) are an ideal drug-delivery platform as they …

Hospitality As A Philosophy Of Care, Freddy Clark

Antioch University Dissertations & Theses

This study examines hospitality as a philosophy of care and a practice of social justice, particularly within marginalized communities. While hospitality is often understood as a gesture of kindness or a function of the service industry, this research reframes it as an ethical and relational practice grounded in human dignity, mutuality, and community formation. It explores how hospitality extends beyond transactional exchanges to become a transformative expression of care that challenges exclusion and affirms belonging. Drawing on interdisciplinary frameworks, the study integrates biblical narratives, including the Good Samaritan and Matthew 25:35–40, philosophical perspectives from Emmanuel Levinas and Jacques Derrida, and …
